Study Of Organo/monmorillonite Composite Materials For Energy Storage

In this paper, the preparation , structure and property of organo/monmorillonite composite materials for energy storage were researched. The following results were obtained by series experiments.1. The inflence of process conditions to ion-exchange coeffcient of organo-monmorillonite from Na-monmorillonite was researched and the correct explanation of the mechanism was rendered. With orthogonal experiments, the optimum conditions in preparation of organo-monmorillonite were obtained. The preparation of organo-monmorillonite from Ca-monmorillonite without Na-treating was also researched, the optimum conditions in preparation of organo-monmorillonite were obtained through orthogonal experiments. The structure of organo-monmorillonite was characterized.2. A new method was presented to prepare the composite phase change materials of paraffin and fatty acids for energy storage by intercalated composition. The process conditions were researched and the structure and properties were characterized.by XRD, IR and DSC. The obtained composite materials have good properties which the pure phase change materials didn't have. The preparation and the property of energy storage of the composite phase change materials for energy storage of polyalcohols were studied.3. Kinetic study of phase change of the composite materials was given by DSC method, the activation energies and the reaction orders of the phase changes in the composite materials were calculated.
